You may have encrypted your message according to the highest standards,
but encryption doesn’t guarantee secrecy. The fact that you sent it is
still detectable. An intercepting party in possession of just a few clues
such as your identity, the receiver’s identify, the time of the message,
surrounding incidents and the like can infer a great deal about the
content of the message in the same way that the NSA can use your metadata
to make inferences about your personality. You need to conceal not just
what’s in the message but its very existence.
The answer? Make your message literally impossible to detect. A team of
researchers from the University of Massachusetts at Amherst and Raytheon
BBN Technologies led by Boulat A. Bash have created a method for doing
just that, cloaking electronic communications so that the communication
can’t be seen. They explain it in a paper titled Covert Optical
